IMPROVEMENT IN FELTlNG-MACHINES.

Specification forming part of Letters Patent No. 210,413, dated December3, 1878; application filed October 25, 1878.

To all whom it may concern:

Be it known that I, HENRY G. ELLSW'ORTH, of Painesville, in the countyof Lake, State of Ohio, have invented a new and useful Improvement inFelting-Machines, of which the following is a specification:

My invention has for its object -the felting of hat-bodies and othermaterial; and consists of a series of vibrating and rotating rolls, saidrolls controlled and operated by a variable train of gears.

In the accompanying drawing, in which similar letters of referenceindicate like parts, Figure 1 is a plan of the machine embodying myinvention; Fig. 2,'a side, and Fig. 3 an end, elevation.

A is the frame. B B are the tables or guideboards for the work, forpassing it into and receiving it from the rolls.

I) b are standards for supporting the bearings of the shafts c c, &c.,to which are secured the upper set of rolls, a a a a, which are capableof a vertical adjustment by means of the springs n allowing the rolls toaccom-' modate themselves to the different thicknesses of materialpassing between them.

The standard b is attached to and forms part of the crosshead 0. One endof the shafts c, to which are secured the lower set of rolls to, alsoruns in bearings attached to the lower crosshead, (3, similar to theupper set.

The vibrating motion is given to the rolls a a by the eccentrics h h onthe driving-shaft g, on one end of which is the driving-pulley l. Theeccentric h is attached to the upper crosshead, 0, running in the guidesd d. The eccentric h is attached in a similar manner to the lowercross-head, O.

The rotating motion is produced by the worm and worm-gear and k on theshafts g and 0.

On the other end of the shaft 0 is the driving-gear m, driving thevariable train of gears f with the intermediates t.

On the shafts c c, and between the standards b I), are the long-toothspur-gears e e,

meshing into each other, their long teeth enabling the upper rolls tohave a vertical adand keyways cut in the shafts c c, to give therotating motion.

The rolls thus represented are corrugated, but can be made of differentshapes that would produce the necessary friction on the material to befelted. I

The object of the variable speed produced by the train of gears f f f ff, giving to each roll an increase of speed'over the one preceding it,causes the work to pass through the rolls perfectly straight, the gears(see Fig. 3) varying from the first gear of twenty-three teeth tonineteen in the lastgear. Any rate of speed can, of course, be obtainedby varying the teeth in the gears.

The combined vibrating and rotating motion thus described resembles therubbing, rolling, and kneading process of hand-labor, but producingbetter, quicker, and more uniform work.

Having thus described my invention, what I claim is 1. In a machine for"felting, the vibrating and rotating rolls a. a, the upper rolls, a,provided with a-vertical adjustment by means of the springs n, incombination with the spurgears e e and variable train of gears f, withtheir intermediates 1', substantially as described, and for the purposeset forth.

2. The combination of the vibrating and rotatin g rolls a a with thecross-heads O (3, guides d d, eccentrics h h, substantially asdescribed.
